Ethylene production in relation to O2 partial pressure of whole pear fruit stored at 2 °C could be described by a Michaelis—Menten equation. This was indicated by the use of a gas exchange model. The ...

Chemists at the University of California, San Diego have demonstrated the feasibility of exploiting sunlight to transform a greenhouse gas into a useful product -- fuel. Chemists at the University of ...

Although oxygen is common throughout the cosmos, most of it isn't in the form that we as humans need to breathe – molecular oxygen, or O 2. Now, researchers at Caltech claim to have created a reactor ...

The gas-exchange rate between streams and the atmosphere is needed to measure in-stream ecological processes and C processing in rivers and streams. Current methods include empirical relationships to ...

University of Western Australia provides funding as a founding partner of The Conversation AU. The oceans have absorbed almost 50 % of the CO2 humans released into the atmosphere, which has driven CO2 ...

CLEVELAND--If humans are going to someday successfully rocket their way to Mars, we're going to have to figure out how to haul enough oxygen along--or better, find a way to make some on the way. But ...

OXYGEN enriched with respect to 18 O has been used to solve the problem of how far oxygen, expired by an animal in the form of carbon dioxide, is identical with that inspired as molecular oxygen.
